these are the two most expensive options on a 997S. I am wondering which option would you spend your money on and why.
X51 give 26 more horsepower and 0-60mph in 0.2 seconds less, while PCCB offers lighter weight at each corners and hence better handling (I realized that the original brakes are more than adequate for stopping power). So really, which one will you pick if you will track the car, and which one you think will have a better track time. Thanks.
